Direct beneficiary of the August-October 2024 nationwide judicial block of X in Brazil: gained roughly 2 million new users in days, briefly became the #1 downloaded app in the country, and Brazilians made up the large majority of new signups during that window — a distinct platform and migration story from Threads (see the "threads" entry, which saw a smaller, Meta-integrated version of the same effect). Built on the open AT Protocol with a public API, and runs its own public status page, unlike X.
